BACKGROUND: Hypotension occurs frequently after epidural anesthesia. Intravenous fluid or vasopressors are among treatment methods to many suggested causes. This study was undertaken retrospectively to determine if the age, weight and height of parturients are related to the local anesthetic dosage in epidural anesthesia for the cesarean section, and if the dosage of local anesthetic influence the change of blood pressure and the requirement of fluid or epherine. METHODS: Sixty-nine parturients were studied by reviewing patients' anesthetic records. During lumbar epidural anesthesia to T4 sensory level, all patients were monitored with mean arterial blood pressure, and prevented from hypotension by administration of Ringer's lactated solution. But if hypotension has been sustained in spite of rapid fluid loading, intermittent ephedrine was injected. We studied the correlation of local anesthetic dosage, decrement of mean blood pressure and total required intravenous fluid volume, and difference of these variables between cases using ephedrine and not using. RESULTS: The volume of local anesthetic to achieve a T4 sensory level was 21.20 3.81ml, which did not correlate with age, weight and height, and did not influence the decrease of mean blood pressure and the volume of administered fluid. But the patients (n=30) who needed ephedrine were adminstered significantly larger dose of the local anesthetic and showed more decrease in the mean blood pressure than those (n=39) who did not. CONCLUSIONS: The dose requirement of local anesthetic during epidural anesthesia for the cesarean section is not determined by the age, weight and height of parturients. But when larger dose of local anesthetic is administered, the patients seem to be more hypotensive and need ephedrine as well as intravenous fluid administration.

Background: Bupivacaine was introduced to be a long-acting spinal anesthetic agent. It has been argued about whether the addition of epinephrine prolongs the bupivacaine action or not. The aim of this present investigation was to find out the effect of additional epinephrine on spinal anesthesia with bupivacaine. Methods: 47 patients undergoing an operation on lower extremity were randomly allocated to 2 groups. All patients were anesthetized by subarachnoid block with 0.5% bupivacaine in 8% glucose, which was mixed with 0.2 ml of normal saline in group non-E (n=24) and 0.2 ml of 1:1,000 epinephrine in group E (n=23). We evaluated blood pressure and heart rate, the sensory and motor blockade and voiding time after spinal anesthesia. Results: The systolic blood pressure (SBP) at 8 and 10 min after anesthesia were lower in group non-E than in group E (p<0.05). The trend of decreasing diastolic blood pressure was similar in both groups. The heart rate(HR) at 2 min after anesthesia was lower in group non-E than in group E (p<0.05). The sensory block in T10 was produced faster in group non-E (7 min) than in group E (11 min)(p<0.05). And the maximal sensory block level and its reaching time was T7 and 14 min in group non-E, and T8 and 17 min in group E (p=0.12, p=0.11). Two segment regression time was 124 min in group non-E, and 184 min in group E (p=011). The onset time of motor block to Bromage scale 3 was 12 min in group non-E and 16 min in group E (p=0.06). The recovery time from complete motor block to Bromage scale 1 after maximal motor block was 263 min in group non-E, and 278 min in group E. The time at which patients voided after anesthesia was 469 min in group non-E, and 466 min in group E. Three patients urinated by using a urinary catheter in each group. Conclusions: The addition of epinephrine to bupivacaine for spinal anesthesia can slow the decrease in SBP and increase the HR at early stage of anesthesia, and slow the sensory block.

Acute hemorrhagic edema of infancy is an unusual form of leukocytoclastic vasculitis occuring in children from the age 4 months to 2 years. The etiology remains unknown. Numerous studies, however, suggest acute hemorrhagic edema of infancy as an immune-mediated vasculitis in response to a variety of antigenic stimuli. We report a case of an acute hemorrhagic edema of infancy; 11-month-old boy with a history of fever for 3 days and a history of purpuric rash on the extremities, trunk, buttock and oral mucosa for 2 days.

Rosai-Dorfman disease (RDD) or sinus histiocytosis with massive lymphadenopathy (SHML) is a benign, idiopathic histiocytic proliferative disorder affecting lymph nodes as well as extranodal sites. It is accompanied by fever, leukocytosis, elevated erythrocyte sedimentation rate, and polyclonal hypergammaglobulinemia. Although cutaneous involvement in RDD is common, a purely cutaneous disease is very rare. Histologic findings show characteristic large, pale, histiocytic cells exhibiting cytophagocytosis (emperipolesis). Immunohistochemically, these histiocytes are positive for S-100 protein and CD68, but negative for CD1a. The etiology is unknown, although it is thought to be a reactive disorder rather than neoplastic. We report two cases of Rosai-Dorfman disease showing involvement limited to the skin.

PURPOSE: Dermatofibrosarcoma protuberans (DFSP) carries a translocation resulting in the collagen type I alpha 1 (COL1A1)-platelet-derived growth factor beta (PDGFB) fusion gene, which is responsible for PDGFB activation. The purpose of this study is to evaluate the clinicopathological, genetic, and therapeutic features of DFSP in Korean patients. MATERIALS AND METHODS: Clinicopathological features of 37 patients with DFSP were reviewed. Multiplex reverse transcriptase-polymerase chain reaction (PCR) was carried out in 16 patients using formalin-fixed, paraffin-embedded tissues and specific primers for COL1A1 and PDGFB. RESULTS: The mean age of 37 patients was 37.4 years old. The most common tumor location was the trunk. All patients were treated primarily with surgery: 34 (91.7%) cases with Mohs micrographic surgery (MMS) and 3 (8.3%) cases with wide local excision. The median follow-up time was 33.7 months. Two patients, one in each treatment group, demonstrated local recurrence during the follow-up period. The COL1A1-PDGFB fusion gene was expressed in 14 (87.5%) cases, demonstrated by reverse transcriptase PCR analysis. No association was found among the different COL1A1-PDGFB fusion transcripts, the various histological subtypes and clinical features. CONCLUSION: Our results support the effectiveness of MMS in treating DFSP. The COL1A1-PDGFB fusion transcript was observed in 87.5% of patients. Therefore, COL1A1-PDGFB is a useful and accurate tool in diagnosing DFSP in Koreans.

OBJECTIVES: The microdose of gonadotrophin-releasing hormone agonist (GnRHa) has been suggested as a beneficial method of ovulation induction for poor responders. However, the effect of microdose of GnRHa itself has not been evaluated yet. We performed a prospective sutdy to assess the effect of microdose of GnRHa (5 microgram of triptorelin acetate) on the luteinizing hormone (LH) and follicle stimulating hormone (FSH). Secondary objective of this study is to assess how long the down-regulation of gonadotrophin secretion by microdose GnRHa persists. METHODS: Five microgram of triptorelin was injected daily into five normally menstruating women for 7 days starting from cycle day 3. The blood sample was drawn for 12h with 4h interval, then for 6days with 4 h interval and once a day for 14days, In next cycle, same amount of triptorelin was injected into the same subjects daily for 3 days. The blood sample was drawn twice a day for 20days. Serum FSH, LH and extradiol level was measured. RESULTS: The serum LH and FSH level increased rapidly after injection of first GnRHa. The FSH level reached peak (27.53+/-6.34 IU/l) in 5h while LH level reached peak (34.35+/-7.18 IU/l) in 4h. The flare of gonadotrophins persisted even after second and third day injection of GnRHa, although the peak levels were not as high as first injection. The down regulation of gonadotrophin was established in 4-5 days. The estradiol level increased for 4-5 days then decreased. When GnRHa was given for 7days, the estradiol level began to rise 7-8 days after last injection; when given for 3days, the estradiol level began to rise 3-6 days after last injection. CONCLUSION: Even with ultra-low dose of GnRHa, the down-regulation of gonadotrophin could be achieved. The flare-up of gonadotrophin would persist for 3days with this dose. The duration of down regulation was influenced by the duration of GnRHa administration.

We present two patients with clinical features suggestive of a hyperkinetic form of encephalitis lethargica described by von Economo. While undergoing treatment for viral meningoencephalitis, they both developed comatose mentality, oromandibular dyskinesia, chorea, myoclonic jerk, oculogyric crisis, opistotonus, respiratory failure, and autonomic dysfunction. One patient died of autonomic failure while the other improved several months later. In both patients, cerebrospinal fluid exmamination revealed only pleocytosis. A brain MRI and EEG showed no specific findings. In order to control severe hyperkinetism and autonomic failure, medical treatments including L-dopa, clonazepam, and steroid pulse therapy were administereed in both cases while electroconvulsive therapy was tried in one of the cases. However, they all failed. These cases and previous reports informed us of the presence of sporadic form of encephalis.
